March 17 (UPI) -- A University of British Columbia graduate mailed a package to the school that turned out to be a book he had borrowed from the library 64 years earlier.

Susan Parker, a librarian at the university, said a package arrived in January and she opened it to discover a 1931 edition of Horace Kephart's book Camping and Woodcraft: Handbook for Vacation Campers and for Travelers in the Wilderness.

The book had been checked out of the library in 1960 by then-student Robert Murray.

"Most people return overdue books surreptitiously or anonymously," Parker said in a university news release. "I've never received one this long overdue."

The book was accompanied by a letter from Murray, now 83, along with a check for about $70.

Murray wrote that he had made good use of the tome over the years.

"I determined that this book was a treasure -- a light year ahead of anything published on the subject at the time I borrowed it, and it has remained so over anything I've seen published since," he wrote.
